摘要： A method of inserting an intervertebral disc implant into a disc space includes accessing a spinal segment having a first vertebral body, a second vertebral body and a disc space between the first and second vertebral bodies. The method includes securing a first pin to the first vertebral body and a second pin to the second vertebral body, using the first and second pins for distracting the disc space, and providing an inserter holding the intervertebral disc implant. The method also desirably includes engaging the inserter with the first and second pins, and advancing the inserter toward the disc space for inserting the intervertebral disc implant into the disc space, whereby the first and second pins align and guide the inserter toward the disc space.

摘要： A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate head, a two-piece interlocking coupling element which mounts about the curvate head, and a rod receiving cylindrical body member having a tapered socket into which both the screw and the interlocking coupling element are securely nested. The interlocking coupling element includes a socket portion which is slotted and tapered so that when it is radially compressed by being driven downwardly into the tapered socket in the cylindrical body it crush locks to the screw. The securing of the rod in the body member provides the necessary downward force onto the socket portion through a contact force on the top of the cap portion. Prior to the rod being inserted, therefore, the screw head remains polyaxially free with respect to the coupling element and the body. In a preferred embodiment, the cap portion and the socket portion are formed and coupled in such a way that when the cap portion is compressed toward the socket portion, there is an additional inward radial force applied by the cap portion to the socket portion, thereby enhancing the total locking force onto the head of the screw.

摘要： The present invention is a polyaxial locking screw plate assembly for immobilization of vertebral bones, via fixation to surfaces thereof. The assembly includes a plate, having an upper portion and a lower portion, each of which has a pair of tapered holes, into which holes coupling elements and bone screws may be inserted. The upper part of the holes further includes an annularly recessed channel in which a snap-ring is disposed. The coupling elements each have an axial taper which matches the taper of the holes, and an interior semi-spherical concave surface in which the semi-spherical head of a bone screw may be polyaxially mounted. The bone screws are inserted through the holes until the coupling element engages and expands the snap-ring. Once the coupling element is fully seated in the hole, thereby locking the screw in place and the coupling element in the hole, the snap-ring contracts to its undeflected position and prevents the coupling element and screw from backing out of the hole in the event of loosening.

摘要： A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a head, a tubular body having holes in the top, side and bottom thereof, and a rod coupling element. The head of the screw is disposed in the body with the shaft of the screw extending out the bottom hole, such that the body and the screw may initially rotate relative to one another. The rod coupling element has a ball shaped end which seats in the body with the remainder of the rod coupling element extending out of the side hole of the body, such that the rod coupling element and the body are initially polyaxially coupled relative to one another. The ball end of the rod coupling element is disposed on top of the head of the screw. A set screw is provided in the top of the body, the tightening of which causes the ball, head, and body to be crush locked together, thereby preventing further relative motion.

摘要： A compression locking variable length cross-link device having modular components, including rod and/or pedicle screw coupling elements each having a hole which may be disposed co-linearly with respect to other such holes in opposing elements such that a threaded hinge-post may be inserted therein. A nut is utilized to compress the elements together to rigidly secure the elements once they have been properly positioned relative to one another. In an additional set of embodiments, a linkage member having an elongate hole therein may be used to couple similar elements thereto in a similar flexible hinge-post manner such that the elements may be coupled to the linkage member instead of to the opposing elements directly.

摘要： A hook device for use with support rod implantation apparatus, having a rod receiving body polyaxially mounted to a blade portion such that the body may be polyaxially manuevered relative to the blade, for easy rod coupling. The blade portion has a semi-spherical head portion which sits above the lamina. The rod receiving portion is a separate coupling element having lower and upper portions. The lower portion is slotted and tapered, and has a semi-spherical interior chamber in which the semi-spherical head is initially polyaxially disposed. The upper portion has a pair of upwardly extending members, defining therebetween a channel for receiving the rod. The uppermost parts of the upwardly extending members include an threading for receiving a top locking nut. A locking ring is disposed about the coupling element, substantially below the side recess; the top of the coupling element being initially positioned above the lower ledge of the side recess such that the rod, when initially disposed therein, seats against the top surface of the locking ring. When the rod is in place, the top locking nut is tightened to provides a downward force onto the rod. The rod, in turn, applies a force against the locking ring to descend down the tapered lower portion, therein locking the semi-spherical head in the interior chamber of the coupling element, and locking it into position relative to the blade portion. In an alternative variation, a rod retaining sleeve may be provided between the locking ring and the nut.
摘要翻译： 一种与支撑杆植入装置一起使用的钩装置，其具有多个轴向安装到叶片部分上的杆接收体，使得该主体可以相对于叶片多重地被植入，以便于杆联接。 叶片部分具有位于层板上方的半球形头部。 杆接收部分是具有下部和上部的单独的联接元件。 下部是开槽和锥形的，并且具有半球形的内部室，其中半球形头部最初被多次布置。 上部具有一对向上延伸的构件，在其间限定用于容纳杆的通道。 向上延伸的构件的最上部分包括用于容纳顶部锁定螺母的螺纹。 锁定环围绕联接元件布置，基本上在侧凹部下方设置; 联接元件的顶部最初定位在侧凹槽的下凸缘上方，使得当初始设置在其中时，杆抵靠锁定环的顶表面。 当杆处于适当位置时，顶部锁紧螺母被拧紧以向杆施加向下的力。 该杆又向锁定环施加一个力，使锥形下部下降，其中将半球形头部锁定在联接元件的内部腔中，并将其锁定在相对于刀片部分的位置。 在替代方案中，可以在锁定环和螺母之间设置杆保持套筒。
